The Restore Stgpool and Restore Volume commands are very closely related.
Under the covers, most of the code is the same.  The major differences are

o Restore Stgpool restores primary files that have previously been marked as
damaged because of a detected data-integrity error.  This is done regardless of
whether the volume has been designated as destroyed.

o Restore Volume allows you to specify the volume name(s) rather than using
Update Volume to designate the destroyed volume(s).

For restoring a small number of volumes, the Restore Volume is more convenient,
particularly if you are not interested in restoring damaged files on other
volumes.  For restoring damaged files or a large number of destroyed volumes,
Restore Stgpool is preferable.
